Explicit Schur-function formulas are derived for the multigraded Frobenius series of type B fermionic coinvariant rings, including the multiplicity-free GL_2 x B_n decomposition for the two-fermion ring and the sign and standard characters for general parameter counts.

Type $B$ fermionic coinvariant rings
Explicit Schur-function formulas are derived for the multigraded Frobenius series of type B fermionic coinvariant rings, including the multiplicity-free GL_2 x B_n decomposition for the two-fermion ring and the sign and standard characters for general parameter counts.
